Even though at a first glance it might seem logical to decrease the load on the engine while starting, the relatively higher electrical demand not only due to the starter which needs to be beefier in order to overcome the higher compression in a Diesel but also the heating elements required to ensure the cold start ability becomes a matter of concern. No wonder Diesel versions of older trucks had dual batteries while the gasser versions had a single one. I also remember some trucks fitted with an externally-mounted battery under a flatbed, which was an usual mod in my country in order to allow fitting a larger battery which couldn't be placed inside the engine bay.
